Expose AVX (VEX-encoded) versions of the Vector Neural Network Instructions to guest. The bit definition: CPUID.(EAX=7,ECX=1):EAX[bit 4] AVX_VNNI The following instructions are available when this feature is present in the guest. 1. VPDPBUS: Multiply and Add Unsigned and Signed Bytes 2. VPDPBUSDS: Multiply and Add Unsigned and Signed Bytes with Saturation 3. VPDPWSSD: Multiply and Add Signed Word Integers 4. VPDPWSSDS: Multiply and Add Signed Integers with Saturation This instruction is currently documented in the latest "extensions" manual (ISE). It will appear in the "main" manual (SDM) in the future.
